GEORGE IV. T. HARLEY, OF FREDERICK, MARYLAND.

PAPER BOX.

SPECIFICATION forming part of Letters T atc- 1t Le. 399,891, dated March 19, 1889.

Application filed January 10, 1889. Serial No. 295,926. (No model.)

To 4all whom t may concern:

Be it known that I, GEORGE IV. T. HARLEY, a citizen of the United States, residing at Frederick, in the county of Frederick and State of Maryland, have invented certain new and useful Improvements in Pape-r Boxes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, having reference to the annexed drawings, forming a part of this my specification ot' said invention.

My invention relates to that class of paper boxes of thick stock, which, to econoniize room, are usually supplied to the market in a hat or knoekdown7 condition, and which maybe, at the convenience of the user, converted into box form by simply bending up the sides and lockin g the same together by interlocking appliances provided at or near the ends of such sides. v

In the drawings, Figure l represents the blank,7 from which the body of a box or its cover is made. Fig. 2 represents three sides or walls of the blank turned up and locked into a box position, it only requiring the remaining knocked-down wall shown in the figure to be turn ed up and locked to complete the body of thebox or its cover, as the case may be. Fig. 3 is a section in the line fr. .fr of Fig. 2.

The paper blank shown knocked down in Fig. l is creased with a proper tool both longitudinally and transversely, as indicated in dotted lines, and so distinct lines of bend are formed for the four walls of the box, and also for the tlaps formed on the opposite ends of two otl its walls.

A indicates the bottom of the box inclosed by the lines of the bend o u. and l) h. B B are the side wall portions, and C C the end wall portions of the blank. The end wall portions, C C', are each near their respective ends provided with slits, as at d, cut through the blank, the length thereof being sufficient to receive the locking-tongue d of a flap, F. (Shown at each end of the side wall portions, B and li.) Midway of the length-of these slits (l a portion of the stock ot the end walls,

' C C', is cut away, so as to form an opening,

as at e, through the stock of the blank, such opening being in this instance somewhat in the likeness of the letter D, as shown, and forming at each of the ends of the side walls, C C, one part ot' the locking device, which I employ for locking together the said walls B B and C C when they have been manipulated from their knockdown condition shown in Fig. l into the form of a box. The side wall portions, B B', as shown in the iigures, are made with end flaps, as at F. These flaps extend beyond or outside of the lines et bend h and h', and are formed with tongue portions,

as at d,which are adapted to be thrust through the slits CZ of the end wall portions, C C', in the act ot' looking the walls together. Each of these flaps F near the center thereof, as shown, has a circular-formed slit, as g, somewhatin the likeness of a letter D cut through the il ap, thus forming spring-like locking parts c within said slits, which may, simply by pressure, be moved or sprung from one side to the other of the flap F. These locking parts c are precisely ot' such size as to iit snugly within the cut-away openings c, when the locking of the walls together is effected, as will presently be described. In Fig. 2 I have shown the side wall, B, turned up vertically on its creased line a, with its flaps F F brought around aga-inst the vertically-turned-up end walls, C `1, and with its locking-tongues d respectively thrust through slits .d d of the end walls. This thrust of the tongues d d', through said slits is shown to have been continued until the wall B has become vertical and until the extreme ends f of the flaps F have impinged against the bottom A of the box, or shall have been thrust far enough toward the bottom A to bring the spring-like locking parts c of said flaps F into exact register with openings c of the end walls, C C, at which moment the operator, by pressing the locking partsl e out from their slits g of the iiaps F into openings e of the said walls C C', effects the locking together of the walls Bi, C, and C. 3y thus lockin g the parts in juxtaposition it will be seen that a pull applied to withdraw the flaps and release the wall B from its position shown in Fig. 2 will be resisted by the contact of the locking parts c against the end walls, (l C', while thus seated in the open- IOO ings e of said end Walls; but by simply apply- .ing pressure against the parts e', so as to force them out of their seats in the openings e and back into their normal positions Within the slits g of said flaps, the flaps may at once be Withdrawn from the slits (Z d of the end Walls and the Walls B C C turned down from their position shown in Fig. 2 to their flat or level position shown in Fig. l. Having locked the Wall B, for example, to the respective ends of the end Walls, C C', as shown in Fig. 2, the Wall B may now by the same manipulation be locked to the opposite ends of the end Walls, thus completely converting the blank shown in Fig l into a box. Itis apparent that the cover of a box, as well as its body portion, may be made as above described, the @over being of course made of somewhat greater area than the body it is to fit upon. Stops, as on., out in the side Walls, B B', and turned 2o down, as shown, serve to stay the end walls, (l C, in position, as shown iu Fig. 2.

I claim- A paper box which comprises in its construction one or more Walls having end flaps, F, provided Wi th locking parts e', in combination With one or more Walls provided with a slit, CZ, and an opening, e, substantially as and for the purpose described.

In testimony whereof l hereunto affix my 3o signature in presence of two witnesses.

GEORGE WV. T. HARLEY.
